ABSTRACT:
Disclosed is a solid-state camera comprising a solid-state image sensor element composed of a plurality of planarly arranged units of picture element cells, drive means for supplying a pulse power source thereto, signal process means for obtaining a picture image signal by processing an output signal from each of the unit of picture element cells, detection means for generating a detection signal based on an output voltage value corresponding to the picture image signal, and sensitivity adjustment means for generating a sensitivity adjustment signal to adjust sensitivity required based on the detection signal in each the unit of picture element cells. This camera controls output signals for read transistors correponding to the respective picture element cells and the respective picture element cells in a unit row at the same time, and adjusts an output voltage value from each unit of picture element cells based on an output voltage value of each unit of picture element cells in a previous line, frame or field by stop signal registers for stopping output signals of the picture element cells.
